Title: Producing lead acid electric storage battery electrodes
IPC: H01M4/82
Filed: 1979-09-07
Abstract: A method of producing electrodes for lead acid storage batteries includes expanding a strip of lead or lead alloy to leave an unexpanded central land 14 and an unexpanded selvedge 12 on each edge of the strip. One or more lozenges of metal are sequentially removed from the land leaving holes 30 and 32 and simultaneously one or more portions of metal are removed from each selvedge leaving projecting portions 38.

Patent GB-2055481-A (GB)
Title: Staying system for a mast
IPC: E04H12/20
Filed: 1980-07-04
Abstract: This invention relates to the control and adjustment of the tension in stays used for locating tall structures such as radio masts. A tension sensing device 15 is connected between a stay cable 12 and an anchor 13. The device includes a piston/cylinder unit which acts on a crosshead to which the cable 12 is attached. The crosshead is slidably mounted on a chassis which acts together with it as the normal tension connection between the cable 12 and anchor 13. The sliding movement available to the crosshead provides sufficient lost motion to enable the piston/cylinder unit to take over the tensile force. The pressure in the piston/cylinder unit gives an indication of the tensile force in the cable 12. Modifications of the device 15 are described, which are additionally capable of tensioning the cable 12. <IMAGE>

Title: Note dispensing system
IPC: G07F19/00
Filed: 1980-10-03
Abstract: A banknote dispensing system includes an operator panel having a keyboard for initiating transaction requests, a dispensing chamber 58 adjacent to the panel for receiving banknotes dispensed by feed means 52 and a transporter 54 in response to an operator request, and a lockable access door 40 to enable the operator to gain access to the chamber to remove dispensed notes.

Patent GB-2087596-A (GB)
Title: Apparatus and Method for Controlling a Variable in Accordance with a Schedule
IPC: G05D16/20
Filed: 1981-10-19
Abstract: A memory (15) is programmed (14) to store a desired schedule of gas pressure to be attained at regularly spaced intervals of time. Signal generators (18, 20) generate respectively, a control signal and reference signal representative of the pressure to be attained at a next time and the given time reference. The gas pressure is sensed by a transducer (8) and compared (26) with the reference signal to form an error signal (30). The control signal is then adjusted (22) in response to the previously generated error signal to provide an adjusted signal for controlling the gas pressure (16). By this means the gas pressure can be controlled in accordance with a schedule calling for rapid and substantial variation of magnitude. The apparatus is stated to be applicable to spray casting processes. <IMAGE>

Title: Document processing systems
IPC: G06K13/02
Filed: 1981-12-03
Abstract: A method and apparatus for handling and processing first and second interrelated documents (13, 15) positions the first document (13) at a first predetermined location (12), and the second document (15) at a second predetermined location (14) adjacent the first location. Once the first document (13) is transported from the first location into the processing station, the second document (15) is then transferred from the second to the first location, for subsequent transport from such first location to the processing station. The order in which documents are processed is therefore automatically ensured, so that errors can be minimised. In particular photocells 91, 94 control the actuation of feed roller 81 at the second location (14). <IMAGE>
